Hey, There's like this darkish line on my iPhone and iPad when I open the Photos app. This scared the ding **** out of me the first time I saw it but then I realized in was a software issue when it disappeared as I swiped up to close the app. It's really weird because it's extremely faint but I can't seem to catch it in screenshots. I know for a fact this is a software issue because it doesn't show up in any other apps. It also changes from horizontal to vertical depending on how I turn my iPhone. Can everyone please just check your own iPhone or iPad to make sure I'm not the only one? I'm on the 18.2 developer beta by the way. Thanks!

I'm attempting to use AVExternalStorageDevice.requestAccess on iOS 18 using Xcode 16. When calling requestAccess, a dialog does appear, but the completionHandler closure is never called to indicate whether access was granted. If using the async version, the function just never returns. Calling requestAccess also results in a mediaServicesWereReset (-11819) error without fail. Supposedly, "the system only presents the dialog to a person the first time your app calls the method." That also doesn't appear to be the case. The dialog appears every time requestAccess is called, regardless of previous invocations and whether "Allow" or "Don't Allow" was selected. The dialog itself says "You can change this in Privacy settings." I cannot find this permission anywhere in the Settings app, neither under Privacy & Security nor under the app-specific settings page. Has anyone else experienced these issues? Am I missing something here? I did suspect permissions issues and tried adding a NSRemovableVolumesUsageDescription entry to the app. This did not appear to change anything.

I'm experiencing a significant limitation with MusicKit's Dolby Atmos implementation on macOS and would appreciate clarification on whether this is intended behavior or if there are solutions available. When streaming Dolby Atmos content through MusicKit's ApplicationMusicPlayer, the output is limited to 2-channel stereo, even when: Audio MIDI Setup is configured for 7.1.4 (12-channel) output The same tracks play in full multichannel through the native Apple Music app Dolby Atmos is set to "Automatic" in Apple Music preferences Please let me know if there is anyway to enable this. If not, is this documented anywhere? Thanks!

i tried combine speech detector and speech transciber to anlayzer. but speech detector is not speech module. please help me

Can anyone please guide me on how to use SFCustomLanguageModelData.CustomPronunciation? I am following the below example from WWDC23 https://wwdcnotes.com/documentation/wwdcnotes/wwdc23-10101-customize-ondevice-speech-recognition/ While using this kind of custom pronunciations we need X-SAMPA string of the specific word. There are tools available on the web to do the same Word to IPA: https://openl.io/ IPA to X-SAMPA: https://tools.lgm.cl/xsampa.html But these tools does not seem to produce the same kind of X-SAMPA strings used in demo, example - "Winawer" is converted to "w I n aU @r". While using any online tools it gives - "/wI"nA:w@r/".

I often find when doing basic actions in MusicKit it is incredibly slow compared to Apple's Music App. I've tried different versions, devices, networks, Apple's sample code, it all throughout the last several years, and it is all the same. Does anyone else have this issue?

tvOS 18 doesn't provide passthrough of multichannel audio for streaming apps offering content where it it promoted as available. This is true for devices for which the functionality existed before the 18.0 tvOS update. What's more, the 18.1 Public Beta did not provide a resolution for the issue. All streaming apps appear to be affected. Notably, Home Sharing does not appear to be affected, and continues to provide multichannel audio as it did before the 18.0 update.

I am trying to use SpeechDetector Module in Speech framework along with SpeechTranscriber. and it is giving me an error Cannot convert value of type 'SpeechDetector' to expected element type 'Array.ArrayLiteralElement' (aka 'any SpeechModule') Below is how I am using it let speechDetector = Speech.SpeechDetector() let transcriber = SpeechTranscriber(locale: Locale.current, transcriptionOptions: [], reportingOptions: [.volatileResults], attributeOptions: [.audioTimeRange]) speechAnalyzer = try SpeechAnalyzer(modules: [transcriber,speechDetector])

Hi all, we are in the business of scanning documents and barcodes with the camera system of mobile devices. Since there is a wide variety of use cases, from scanning tiniest barcodes and small business cards to scanning barcodes or large documents from far distances we preferably rely on the triple camera devices, if available, with automatic constituent device switching. This approach used to be working perfectly fine. Depending on the zoom level (we prefer to use an initial zoom value of 2.0) and the focusing distance the iPhone Pro models switched through the different camera systems at light speed: from ultra-wide to wide, tele and back. No issues at all. Unfortunately the new iPhone 16 Pro models behave very different when it comes to constituent device switching based on focus distance. The switching is slow and sometimes it does not happen at all when the focusing distance changes. Especially when aiming for a at a distant object for a longer time and then aiming at a very close object that is maybe 2" away. The iPhone 15 Pro here always switches immediately to the ultra-wide camera, while the iPhone 16 Pro takes at least 2-3 seconds, in rare cases up to 10 seconds and sometimes forever to switch to the ultra-wide camera. Of course we assumed that our code is responsible for these issues. So we experimented with restricting the devices and so on. Then we stripped more and more configuration code but nothing we tried improved the situation. So we ended up writing a minimal example app that demonstrates the problem. You can find the code below. Execute it on various iPhones and aim at far distance (> 10 feet) and then quickly to very close distance (<5 inches). Here is a list of devices and our test results: iPhone 15 Pro, iOS 17.6: very fast and reliable switching iPhone 15 Pro, iOS 18.1: very fast and reliable switching iPhone 13 Pro Max, iOS 15.3: very fast and reliable switching iPhone 16 (dual-wide camera), iOS 18.1: very fast and reliable switching iPhone 16 Pro, iOS 18.1: slow switching, unreliable iPhone 16 Pro Max, iOS 18.1: slow switching, unreliable Questions: Does anyone else have seen this issue? And possibly found a workaround? Is this behaviour intended on iPhone 16 Pro models? Can we somehow improve the switching speed? Further the iPhone 16 Pro models also show a jumping preview in the preview layer when they switch the constituent active device. Not dramatic, but compared to the other phones it looks like a glitch. Thank you very much!

My App is live on app store , user are using it with iPhone 16 pro max and they are getting Operation Stopped while combining videos and audios only specifically on iPhone 16 pro max , on every other device its working fine. And When i adding AVAssetExportPresetPassthrough it able to combine videos and audios but not respecting the encoding and without audio. NSArray *compatiblePresets = [AVAssetExportSession exportPresetsCompatibleWithAsset:composition]; if ([compatiblePresets containsObject:AVAssetExportPresetHighestQuality]) { presetName = AVAssetExportPresetHighestQuality; } else if ([compatiblePresets containsObject:AVAssetExportPreset1920x1080]) { presetName = AVAssetExportPreset1920x1080; } else if ([compatiblePresets containsObject:AVAssetExportPreset1280x720]) { presetName = AVAssetExportPreset1280x720; } else { presetName = AVAssetExportPresetPassthrough; } } else { presetName = AVAssetExportPreset1280x720; }

I am working on an app which plays audio - https://youtu.be/VbAfUk_eYl0?si=nJg5ayy2faWE78-g - and one of the features is, on restart, if you had paused playback of a file at the time the app was previously shut down (or were playing one at the time of shutdown), the paused state and position in the file is restored exactly as it was, on restart. The functionality works. However, it seems impossible to get the "now playing" information in iOS into the right state to reflect that via the MediaPlayer API. On restart, handlers are attached to the play/pause/togglePlayPause actions on MPRemoteCommandCenter.shared(), and the map of media info is updated on MPNowPlayingInfoCenter.default().nowPlayingInfo. What happens is that iOS's media view shows the audio as playing and offers a pause button - even though the play action is enabled and the pause action is disabled. Once playback has been initiated (my workaround is to have the pause action toggle the play state, since otherwise you wouldn't be able to initiate playback from controls in a car without initiating it once from a device first). I've created a simplified white-noise-player demo to illustrate the problem - simply build and deploy it, and then start the app, lock your device and look at the playback controls on the lock screen. It will show a pause button - same behavior I've described. https://github.com/timboudreau/ios-play-pause-demo I've tried a few things to narrow down the source of the issue - for example, thinking that not MPNowPlayingInfoPropertyPlaybackProgress and MPMediaItemPropertyPlaybackDuration might be the culprit (since the system interpolates elapsed time and it's recommended to update those properties infrequently) on startup might do the trick, but the result is the same, just without a duration or progress shown. What governs this behavior, and is there some way to explicitly tell the media player API your current state is paused?

Since upgrading to tvOS 18, the above function isn't working for me in converting a stream with these formats. It does work in decoding AAC, however. https://developer.apple.com/documentation/audiotoolbox/1503098-audioconverterfillcomplexbuffer?language=objc I pass a valid ioOutputDataPacketSize in, but it always comes out as zero. Has anyone else observed this too? I wonder if this is related to the issue being discussed widely about 5.1 sound being broken for many people after upgrading to tvOS 18? https://discussions.apple.com/thread/255769102?login=true&sortBy=rank EDIT: further information; the callback gets called once, asking for 1 packet (which is ok). I give it one packet and return noErr. However, after this, the callback is never invoked again. Must be a bug? EDIT2: the same code continues to work correctly on macOS in decoding the same audio stream.

I have an HDR10+ encoded video that if loaded as a mov plays back on the Apple Vision Pro but when that video is encoded using the latest (1.23b) Apple HLS tools to generate an fMP4 - the resulting m3u8 cannot be played back in the Apple Vision Pro and I only get back a "Cannot Open" error. To generate the m3u8, I'm just calling mediafilesegmenter (with -iso-fragmented) and then variantplaylistcreator. This completes with no errors but the m3u8 will playback on the Mac using VLC but not on the Apple Vision Pro. The relevant part of the m3u8 is: #EXT-X-STREAM-INF:AVERAGE-BANDWIDTH=40022507,BANDWIDTH=48883974,VIDEO-RANGE=PQ,CODECS="ec-3,hvc1.1.60000000.L180.B0",RESOLUTION=4096x4096,FRAME-RATE=24.000,CLOSED-CAPTIONS=NONE,AUDIO="audio1",REQ-VIDEO-LAYOUT="CH-STEREO" {{url}} Has anyone been able to use the HLS tools to generate fMP4s of MV-HEVC videos with HDR10?

Is anyone experiencing an issue with initial ‘AVAudioSession.sharedInstance().outputVolume’ returning 0 after updating to iOS 18.0? I’m observing the outputVolume of AVAudioSession, and when I adjust the device volume, the change value returns correctly. However, when I call AVAudioSession.sharedInstance().outputVolume to get the current volume before knowing the change value, it returns 0, even though the device volume is not actually 0.

I've been generating new Audio Unit Extension apps with Xcode 16 (and newer), and although they generally work initially, it is easy (although I'm not sure how to do it reliably) to cause the app to no longer be able to instantiate the audiounit. Generally the call to AVAudioUnit.findComponent fails and SimplePlayEngine hits the fatalError("Failed to find component with type...") In the most recent project, merely adding files to the extension (without making any use of them) caused it to go off the rails. If I "Archive" the app+plugin, there is no audio unit extension in the bundle. If I switch to the audiounit extension and build it it's fine. If I look at the build folder in Library/Developer/Xcode/project_folder the extension_name.appex is there. Any ideas? If I can coax an unmodified audio unit extension project to exhibit this behavior I'll attach it here. Right now what I have has code I don't want to share.

Safari is supposed to support animated AVIF images since version 16, but the ones I've tested perform very poorly, even on an M4 Mac Mini running Sequoia 15.1.1. I believe Safari delegates decoding to the operating system itself, so this issue also happens in Live Preview in the finder, when I try to preview a file. Sample file here: https://s3.us-west-2.amazonaws.com/cdn.paintera.org/test/sample.avif 322KB file, 5 seconds long, 12fps This plays perfectly on Chrome on Mac OS, but is slow and laggy on Safari and Live Preview (it takes about 6.5 seconds to finish the 5 second video). Does anyone know how to fix this or workaround this issue?

When my CarPlay connects and tries to play music it plays it through the vehicles phone speakers. If I make a phone call and then hang up it pushes the sound back to the vehicles stereo speakers. Does anyone have a fix for this because this is very annoying. Sometimes it will just switch to the phone speakers and I have to complete the process again.

Hi: I am working with the ObjectCapture frameworks and sample code. Everything works great. We are trying to go from capturing 12MP images as in the sample code to capturing 48MP 6048 × 8064 images. We can't seem to get it to work. Any advice here?

Since iOS 12 it has become difficult to detect the end of playback using the system music player. In earlier iOS versions, the now playing item would be set nil and you would receive a notification that the player stopped. In iOS 12 and later, nowPlayingItem still contains the current song and the only notification you get is MPMusicPlayerControllerPlaybackStateDidChangeNotification with the playbackState set to MPMusicPlaybackStatePaused. Pressing pause in my car (or any remote access) generates the same conditions making it difficult to correctly detect the difference. It would be nice if they added a notification that playback was done (similar to the other players). Any suggestions?
